Incidence of Pest on Different Cultivars of Paddy under Various Cultivation Methods in Relatoin to Weather Parameters

Abstract

The field experiment, “Studies on effect of different paddy cultivars with various cultivation methods of paddy in relation to weather parameters.” was carried out during kharif, 2018 at Agricultural Research Station Farm,VadgaonMaval, Tal. Maval, Dist. Pune. It was laid out in split plot design with three replications. There were sixteen treatment combinations comprising of four varieties viz., VDN-3-51-18 (Indrayani), VDN-99-29 (PhuleSamruddhi), IET-13549 (Bhogawati) and RDN-99-1 (Phule Radha) and four cultivation methods viz., M1 : Four Point Agro Technique (Char Sutri Method), M2 : Drilling at 22.5 cm, M3 : Saguna Rice Technique (SRT) and M4 : Modified Direct Seeded Rice Technique (MDSRT). The lower pest population was observed in paddy variety VDN-99-29 (Phule Samruddhi) followed VDN-3-51-18 (Indrayani) and higher incidence with IET-13549 (Bhogawati) and RDN-99-1 (Phule Radha). Pest Incidence was more with drilling at 22.5 cm and lower with Modified Direct Seeded Rice Technique (MDSRT). There was positive correlation between maximum temperature, morning relative humidity, BSS, growing degree day and canopy temperature with incidence of leaf folder and brown plant hopper but negative correlation with minimum temperature, evening relative humidity. Therefore, it would be suggested to Farmers to go for adopt VDN-99-29 (Phule Samruddhi) variety, sowing with Modified Direct Seeded Rice Technique (MDSRT) for for minimum attack of rice pest.
